Title: Water permeable mat - prevents erosion of river banks, has bulky fibrous batt secured to rot resistant base
IPC: E02D17/20
Filed: 1973-05-10
Abstract: A water permeable mat for preventing erosion of river banks etc. includes a bulky fibrous batt of natural (pref. coconut, sisal) or synthetic (un)textured fibres chemically or mechanically bonded together is secured e.g. by stitching, adhesive, or needling to a rot-resistant knitted woven or non-woven water permeable support web. The structure of the batt is sufficiently open to allow it to retain particulate filtering material (e.g. sand gravel, earth) which is pref. positionally fixed by an adhesive emulsion. Movement of the particulate material in the batt is reduced making the mat more effective and easier to transport.

IPC: F27B1/16
Filed: 1982-12-23
Abstract: In a shaft furnace for burning limestone or similar raw materials, gaseous, liquid or solid fuels are supplied through fuel supply pipes to the burning zone of a furnace shaft. To permit the simultaneous supply of at least two different fuels, the fuel supply pipes are arranged as multiple fuel lances. The fuel lances extend inwardly from the shaft furnace wall through the preheating zone into the first part of the burning zone. The fuel lance is a double tube member made up of an inner tube laterally enclosed by an outer tube forming an inner fuel supply passageway and an outer annular fuel supply passageway. Two separate fuels can be introduced into the burning zone, one flowing through the inner passageway and the other through the outer annular passageway. The two different fuels can be supplied in varying proportions without any changeover operations.

Abstract: EMPHASIS IS CONTROLLED SPEECH SYNTHESIZER          Abstract of the Disclosure Disclosed is a system for synthesizing emphasis-controlled speech from stored signals representative of words precoded by a phase vocoder having analysis bands which are wide relative to the voice harmonic frequency spacings.  The stored signals comprise short-time Fourier transform parameters which describe the magnitude and the phase derivative of the short-time speech spectrum.          Speech emphasis-controlled synthesis is achieved by extracting the stored signals of chosen words under control of a pitch-duration signal, by concatenating the extracted signals, by modifying the magnitude parameters of the extracted signals to effect a desired speech intensity, by interpolating the extracted parameters, and by decoding the resultant signals in accordance with phase vocoder techniques.

Abstract: ABSTRACT     The metallization of through-holes in ceramic green sheets where the through-holes are of a diameter which may be less that 0.1 millimeters has been extremely difficult where the through-holes are metallized by silk-screening a conductive paste through a molybdenum mask onto the ceramic green sheet which is mounted on a flat, stable carrier thus completely filling the through-holes.  By substituting a carrier capable of absorbing at least some of the components of the conductive paste for the flat, stable carrier it has been discovered that plated through-holes may be obtained by simply removing the carrier from the green sheet.  The so removed carrier retains the central portion of the deposited conductive paste and leaves a thin conductive lining in the through-hole.

Abstract: ABSTRACT OF THE DISCLOSURE           It has hitherto been impractical to use a computer to optimise the control of a plurality of operating stations in a hot metal handling operation such as an aluminum reduction pot line because of the difficulty of communica-ting between the computer and the pots.  A hard wire system is impractical in a large operation involving numerous pots, furnaces, or the like.  The invention solves this problem by taking advantage of the fact that the pots, furnaces, or the like are serviced by a crane, usually an overhead crane on rails, which adds raw materials to the pots, furnaces, or the like and removes molten metal.  The crane is provided with a data acquisition unit which can measure various process variables such as weight, temperature, etc. and an optical telemetry link which provides two-way communication between the crane and the computer.

Abstract: ABSTRACT OF THE DISCLOSURE A method of improving homogeneity in batch digestion of ligno-cellulose containing material in a digester, the circulation system of which is designed so that the cooking liquid is drawn off from the digester via a strainer girdle, heated in a calorisator and returned to the top and bottom, respectively, of the digester.  During the heating phase the digester is subjected to boiling-up brought about by periodically heating only from below by a substantial supply of heat via the bottom circulation with a cooking liquid flow of 1-15m3/minute, preferably .3-8m3/minute, at the same time as the top circulation is held closed and pressure drop in the digester is prevented.  The number of the boilings-up and the time intervals are adjusted to the digestion schedule in question, so that the greatest possible heat homogeneity in the digester is obtained during the entire part of the digesting process when delignification takes place.

Abstract: COMMON CONTROL FAILURE ALARM APPARATUS               -Abstract of the Disclosure A local alarm circuit and a remote alarm circuit carry out a plurality of failure monitoring and alarming functions for each of a plurality of digital groups (digroups), of time division multiplexed channels that are time multiplexed together on to a common bus.  The local and remote alarm circuits utilize common control techniques and are of a similar circuit configuration.  Each alarm circuit comprises an alarm timing store having a shared recirculating memory, and an alarm status store with a shared recirculating memory.  The timing store serves to integrate and time failure indications for each of the digroups, and the status store maintains a continuing real time record of the alarm status for each digroup.  When the timing store counts out a predetermined failure duration for a given digroup, the alarm status record for the digroup is changed and an alarm signal is generated.  Once an alarm is registered for a digroup, the timing store then serves to integrate and time failure-free indications for the digroup.  That is, it counts out a predetermined failure-free duration (after appropriate maintenance action has been taken) before it terminates the alarm state record in the status store and the alarm signal.

Abstract: ABSTRACT OF THE DISCLOSURE         In a prime mover control system, control over the prime mover is dependent, in part, upon the validity of a reference signal to the control system.  Circuitry is provided between a reference signal generator and the control system whereby under normal conditions the reference signal to the control system is the same as the output of the reference signal generator, However, in the reference signal generator output becomes invalid, then a stored reference signal may be substituted for the reference signal generator output by switching from a first signal channel to an alternate second signal channel, each channel selectably interconnecting the reference signal generator and the control system. The output of the second signal channel is periodically updated to follow, with a time lag the reference signal generator output except when an invalid reference signal generator output is detected whereupon the update of the second signal channel is frozen at a last valid reference signal which is then input into the control system.
